ISAAC N. MILLS, OF DOVER, ASSIGNOR OF TVVO-THIRDS TO WILLIAM HUSTON ANDHENRY WIOKERSHAM, BOTH OF WILMINGTON, DELAWARE.

HEATING,\COOLING, A'ND VENTI'LATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 283,637, dated August21 1883.

' Application filed March 2, 1883. (No model.)

To all whom it may concern:

Be it known that I, ISAAC N. MILLS, of Dover, Kent county, Delaware,have invented certain Improvements in Heating, Ventilating, and CoolingApparatus, of which the fol- J lowing is a specification.

The object of my invention is to more offectually ventilate, heat, orcool dwellings and other bulldings, vessels, cars, 8rd, than can beeffected by appliances ordinarily employed for that purpose; and to thisend I combine with the structure intended to be ventilated, heated, orcooled certain conduits, heating or cooling appliances, or both, and anejector,

1 5 which may be operated to exhaust the air from the chambers withoutthe use of engines.

The drawings represent, in Figure l, a sectional elevation of adwelling-house and appliances to carry out my invention, and Fig.

2o 2 a plan section of the ejector device used.

I have represented at Athe walls of a house,

inclosing several chambers, a b c d e f g, arranged as in an ordinarythree-story and backbuilding edifice. In the upper chamber, 9,

'2 5 preferably a loft or other unoccupied room, I

place a casing or tank, B, which communicates through a tube, 1', with aflue, whereby fresh air may-be introduced into the tank.

The tank communicates through an opening,

. 0 u, (shown in dotted lines,) with a conduit, D,

consisting of a main' tube and laterals or branches as may be necessary,all so arranged 5 'Within the tank B may be'arranged a coil, E,

of pipe, connecting with a pipe, j, leading to the boiler of a furnace,F, from which steam or water may be passed to the coil to heatthe airintroduced into the chambers; or a con- 40 nection may-be made betweenthe pipe j and a refrigerating apparatus, H, so that a cold fluid may becirculated through the coil E to cool the air passing through the tankB. By

' this means fresh air from a high point, where it'will not be vitiatedby sewer-gas or other impurities, may be taken to the tank B and therecooled or heated, and then distributed to the various chambers of thehouse.

In order to insure positively a flow of .air'

[ munication with openings m, near the floors of the different chambers,and this conduit K, I extend to a chamber, L, containing an ejector, M,of any suitable character, to create an exhaust that will insure theflow of air from the different chambers into said opening an, andthrough the ejector to a discharge-flue, N, which may lead to a sewer orelsewhere. To avoid the use of an engine to create this downdraft I usean ejector which will operate effectively under the action of a fluidjet, (for instance, such an ejector as is described in the patent to*Wickersham and Huston, dated February 20, 1883,) a steam -pipe, 3,leading from the boiler of the furnace to the ejector, and supplying themotor -power. By this means I am enabled not only to supply fresh air,either warm or cold, to the various chambers, but I can. also withdrawthe foul air, and by such withdrawal also facilitate the entrance ofthat which is is uncontaminated; and I secure the advantages resultingfrom passing cold 7 5 air downward into the chambers, and avoid the lossof heat which results when Warm air is drawn from the upper portions ofthe rooms. It will'be also .seen that by the use of an ejector I amenabled to secure the desired draft without the use of any niechanicalmotors, which, in the majority of cases, cannot be employed in privatedwellings.

I claim 1. The wit-l1in-described improvementin ap- 8 5 paratus forheating, cooling, and ventilatng structures,the same consisting in thecombination of a tank, B, arranged in an upper v chamber andcommunicating with an external flue, conduits D, leading from said tankto 0 openings 1), near theceiling of each chamber, a-conduit, K,communicating with openings m, near the floor of each chamber, and withan ejector, M, all substantially as described.

2.- 'Ihecombination, with a structure, of the tank B, conduits D K,communicating with openings 12 m, ejector M, and heating and coolingapparatus arranged to heat or cool the air in the tank B, substantiallyas set forth.

In testimony whereof I have signed my name 10: to this'specification inthe presence of two subscribing witnesses.

I. N. MILLS.
